چکیده

Abstract The prober with an immovable lander and a movable rover is commonly used to explore the Moon’s surface. can complete detection on relatively flat terrain of lunar surface well, but its efficiency deep craters mountains low due difficulties reaching such places. A lightweight four-legged landing walking robot called “FLLWR” designed in this study. It take off land repeatedly between any two sites wherever craters, or other challenging landforms that are difficult reach by direct ground movement. integrates functions rover, including folding, deploying, repetitive landing, walking. control method via compliance proposed solve critical problem impact energy dissipation realize buffer landing. Repetitive experiments five-degree-of-freedom gravity testing platform performed. Under conditions vertical velocity 2.1 m/s loading weight 140 kg, torque safety margin 10.3% 16.7%, height 36.4% 50.1% for cases without additional horizontal disturbance 0.4 m/s, respectively. study provides novel insight into next-generation exploration equipment.

Force Control in One Legged Hopping Robot while Landing

In this paper, the issue of control of impact forces generated during the interaction between the hopping robot toe and the ground during landing has been considered. The force thus generated can damage the robot altogether. With the objective to control these impact forces impedance control strategy has been applied to the hopping robot system. The dynamics pertaining to the impact between rob...

Four legged walking robot control using neural networks

This paper presents neural network (NN) control of planar four-legged walking robot. The control system consists of a neural controller, standard PD controller and walking robot. Proposed NN is employed as an inverse controller of the robot. In addition to feedforward connections from the input layer to the hidden layer and from the hidden layer to the output layer, there is also feedback conne...

Aramies: a Four-legged Climbing and Walking Robot

This article describes the four-legged walking integration study ARAMIES and the developed control software approach. Furthermore, we analyze a first walking experiment carried out. We explain how CPG-like rhythmic motion patterns can be produced on the basis of Bezier-splines, resulting in a very simple and flexible way to produce complex walking trajectories which can be modulated in phase, f...
